ajax response to variable

[n3b]

I'm trying to assign the response of an Ext.ajax.request to a variable but I'm failing at every turn. Basically I want to do something like:

function getAjaxJson( url, method ){

		var json;
		Ext.Ajax.request({
			url : url, 
			method: (method==null) ? 'GET' : method,
			timeout: 180000,
			success: function ( response ) {
				json =  Ext.decode(response.responseText);
			},
			failure: function ( response ) { 
				Ext.MessageBox.alert('Failed', response.responseText);
			},
			scope: this
		});

		return json;
}

var mydata = getAjaxJson("someurl");

I know the scope must be wrong (I see the json variable getting populated then becoming undefined after the callback terminates) - I need some pointers.

All clues welcome.

Cheers,
n

your problem is not scope but the fact that you don't know that Ajax requests are asynchronous.
